service HTTP requests. If you expect to serve complex pages with many
images or other components that are fetched separately, or if any
pages may take a long time to send, then it may be useful to increase
the number of server threads. For most uses, however, the connection
queuing in the TCP/IP stack and the speed with which each page is
generated, means that a single thread is usually adequate.</P

depends on the importance of the server relative to the rest of the
system. The default is to put them in the middle of the priority range
to provide reasonable response without impacting genuine high priority
